Cephalosporin, esetshenziswe njengomphakathi we-cefbutan ne-cefazoxime.
I-Sulfuric Acid (104.3ML, 1.92mol) yengezwe emabhodleleni amathathu, bese i-Isophthalic acid (40G, 0.5mol), ivuswe ngo-60h, i-60% i-nitric (37.8G, i-6% Yengeze ngamahora ama-2. Ngemuva kwalokho, ukusabela kokulondolozwa kokushisa ngo-60 ℃ amahora ama-2. Ipholile ngaphansi kwe-50 ° C, bese wengeza ama-100ml wamanzi. Okuqukethwe kuphonswe ekushiseni kwegumbi, kuthululelwe kusihlungi, kufakwe ukususa i-acid yemfucuza, kugezwe amakhekhe, akhishwe kabusha, futhi umkhiqizo omhlophe wawungama-34.4%.
I-20kg noma i-25kg / i-Bucket, ibhakede lekhadibhodi, efakwe ungqimba olumhlophe nesikhwama esimnyama se-polyethylene. 2 ℃ -8 ℃ Omile, indawo epholile, kude nesitoreji esikhanyayo, esebenza iminyaka emi-2.
